JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If your account was over quota for more than a day or so, your forms would have been disabled and would not have been accepting new submissions during that time. Your users would have been presented with an "over quota" error when trying to complete submissions. If your forms were disabled, there would have been no new submissions during that time.
If you have any further questions, let us know and we will be happy to help.
